Description
Technical field
Lead wire insulation fixed support on a kind of fuse device that the present invention relates to live line working field.
Background technology
Charged for replacement terminal pole fuse device is the events in operation that charged class often runs into.According to " 10kV overhead distribution live line working guiding book " regulation, to tear on fuse lead-in wire two kinds of methods on pile crown and disconnecting at present open.
Tear pile crown method on fuse open to have been coordinated by electrician in 2 buckets, after in connection, lead-in wire and the screw of upper pile crown are turned on, 1 electrician utilizes the fixing upper lead-in wire of insulating bar, and lead-in wire is kept a safe distance with cross-arm and another electrician simultaneously, and another 1 electrician exchanges fuse device.There are three shortcomings in the method: one is that fail safe is not strong, when the electrician of fixing upper lead-in wire is absent minded, can causes rocking of lead-in wire, there is greatly potential safety hazard; Two is must by exchanging fuse device mutually, and in exchange during phase fuse device, both sides phase terminal is all charged, and measure complexity is covered in insulation; Three is development trends that in 2 buckets, electrician's operation does not simultaneously meet distribution network live line work, and both wastes of manpower, cause again narrow space in insulation bucket, operation inconvenience.
In disconnecting, leads method to be cut off fuse device goes between at nearly insulator end, and completes after fuse device exchanges, then coupled together by the upper lead-in wire disconnected with wedge clamp.The method can be fulfiled assignment by electrician in 1 bucket, but there are two shortcomings: one is that the activity duration is long, is generally 60min, because 10kV circuit mostly is insulated wire, before utilizing wedge clamp connection, needs stripping 6 joints; Two is waste materials, additionally increases operating cost, because connection three-phase goes between needs 3 wedge clamps, 3 bullets and some insulating self-adhesive bands, when upper lead-in wire is 25mm
2during copper cash, the upper lead-in wire of disconnection must be replaced by the lead-in wire in other cross sections, and the cost that every subjob additionally increases is 1000 yuan.
Summary of the invention
